APPARATUS FOR THE MANUFACTURE OF LAMP-BLACK.

SPECIFICATION forming part of Letters Patent No. 801,518, dated July 8,1884.

Application filed January 14, 1884. (No model.)

129 all whom it may concern:

Be it known that I, FREDERICK. PLUMBLY,

of Buffalo, in the county of Erie and State of that the followingdescription of my said invention, taken in connect-ion with theaccompanying sheet of drawings, forms a full, clear, l and exactspecification, whichwill enable others skilled in the art to which itappertains to.

make and use the same.

My present invention has general reference to improvements inmachineryfor manufactur- I ing lamp-black; and it consists, essentially,in

the novel and peculiar combination of parts and details of construction,as hereinafter first fully set forth and described, and then pointed outin the claims.

In the drawings already mentioned, which serve to illustrate my saidinvention more fully, Figure l is a transverse sectional elevation of abuilding fitted up with machineryof my improved construction for themanufacture Fig; 2 is a transverse sectional elevation of a portion ofthe machinery. Fig. 3 is a plan of one of the revolving depositors,portions of which are broken away to expose underlying parts. Fig. 4: isa transverse sectional elevation of a fragment of the depositor and thescraper for removing the carbon deposit.

Like parts are designated by corresponding letters of reference in allthe figures.

The object of my present invention is the production of suitablemechanism for the economical manufacture of lamp black from, preferably,natural gas. "10 attain this result I construct within a suitablebuilding a series of annular pans, A A, supported upon a verticalspindle or shaft, F,-and rotated by means of a worm-wheel, N, and wormO, or any other suitable and convenient mechanism. These pans A Aconsist each of a central L- shaped ring, B, having arms, as shown inFig.

3, and an outer L-shaped ring, 0, secured to V the inner ring by meansof spider'arms D, and supported by means of guy-rods E, havingturn-buckles E, Fig. 2, for tensioning said guy-rods E. Underneath therings and spider-arms is secured an annular disk, F, Fig.

'4, forming, as it were, a bottomfor the pan,

and at the same time a depositing-surface for the lamp-black, ashereinafter to be more particularly referred to.

In constructing this apparatus I prefer to locate two (or more) of thesepans A A, one above the other upon the spindle F, and place underneatheach pan a series of burners, 41, Figs. 2 and 3, from which the gas isburned at f underneath and in close or nearly close contact with thedepositing-surface F. This gas is supplied to the apparatus by means ofa large supply-pipe, 0, havingtwo or more branch pipes, a, (oneunderneath each pan,) and radiating therefrom a large number ofservicepipes, 0, into which service-pipes the'burners d are screwed orotherwise affixed. Above the lower pan, A, I place a hood, H, offunnelsha-ped contour, to convey thehot gases of combustion of theburners d to the central portion ol'the next succeeding higher pan,through the central space of which said hot gases of combustion escapefrom the room in which the ap paratus is placed into the story above,and from whence they are conveyed by the chimney U having the hood a,into the outer atmosphere. In case only two of such pans are employed, Iuse but one of the hoods, H, between thetwo pans; but when more than twoare arranged one above the other I place a hood, H, between every pan,so that the gases of combustion of one set of burners underneath itsrespective pan cannot interfere with the proper burning of the lightsunderneath the higher pan or pans.

In order to keep the pans A A at a correspondingly low temperature, Ifurnish them with a continuous supply of cold water from a water-main,b, and nozzles bathe escape of the same from the pans being effected bymeans of a series of discharge or overflow pipes, a a, located near andrevolving with the spindle F, and discharging into a reservoir, G, fromwhence the waste water is directed to any suitable conductor-pipe, L, bymeans of the pipe e, Figs. 1 and 2.

Owing to the condensation of the gasflames when in close contact withthe depositingplates F of the pans A A, and the imperfect combustionmaintained, the unconsumed carbon of the gas is deposited on the underside of the said pans, from which the carbon (lampblack) is removed bymeans of a series of scrapers, R, consisting of steel wire or othersuitable brushes secured between two strips of iron or other holder, 0,Fig. 4, said brushes or scrapers being located in an open-mouthedtrough, Q. This trough connects with an exhaust-fan, J, or othersuitable motor by means of pipes P in such a manner that a current ofair created by the suction-fan or other propelling motor causes thecarbon removed by the brushes R to drop into the open mouth or a troughand to pass along through the pipe I? and fan J and discharge-pipe I toa suitablyconstructed receiver and separator, (screen,) K. This lattermachine may be of any wellknown and approved construction, or of anyspecial design, a detailed description of which is not deemed necessaryinthe present instance.

The scrapers R are provided with pendulum-poises S, by means of whichthey are al ways kept in an erect position, and yet not so rigidly heldbut that the brushes may follow any undulations in the plane of thepans. WVhen desired, they (the brushes) may be kept in aninoperativeposition away from the disk F by lifting the weights S andkeeping them suspendedin an obvious manner, while, to 'compensate forwear of the scrapers, their journals may be made adjustable, or otherequivalent means (not illustrated) adapted to attain the desired result.

To supply the building with proper ventilation and furnishing theburners with the desired amount of oxygen from the atmosphere, I providethe structure with a suitable number of registers, T, in the floor, andV V in the sides of the building, which said registers may always be soregulated as to allow of the admission of a suitable supply ofatmospheric The machinery described may be revolved by means of a mainline of shafting, M, and belting O, of leather, metal, 850., manywellknown manner, and, to attain a healthy atmos phere in the building,proper ventilators, V, as shown in the drawings, are employed.

It will be readily observed that, instead of the exhaust-fan J andconductor-pipes P P, I

may employ other means for conducting the lamp-black removed from thedepositor F to the receiver K-such as a screw or belt conveyer oranalogous device-which will accomplish the object in view. Such devicesare well known, and, for this reason, mechanical equivalents of theexhaust fan shown.

In case that fine particles of carbon should separate from the depositorF and float in the atmosphere, which would cause a loss of the finestpart of the lamp-black on account of the upward current of air in thebuilding, Ishall surround the entire apparatus with a jacket, (notshown,) or inclose thesame with suitable partition-walls to prevent theescape of such floating particles of carbon.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent of the United States 1. In machines formanufacturing lampblack, the combination, with the pans A A, revolvingby means of mechanism substantially as described, of the hood H,scrapers R, pipes Q and P, exhaust-fan J, and receiver K, as stated.

2. The combination, with the pipe P, having the open-mouthed branchQ,'of the brush scraper B, said scraper :being pivoted, as de scribed,and provided with the pendulumrpoise S, as and for the object specified.

3. In machinery for manufacturing lampblack, a depositor consisting,essentially, of an annular pan, A, having centrally an L-shaped,

ring, B, an annular L-shaped outer ring, 0, a series of spider-arms, D,and an annular disk, F, said depositor being secured to the uprightspindle F, and supplied-with means, substantially as described, forkeeping it at a low temperature, as stated.

In testimony that I claim the foregoing as my invention I have heretoset my hand in the presence of two subscribing witnesses.
